This sash construction comprises, generally, hollow sheet metal stiles formed up of comparatively thin sheet metal, and a wear strip along one of the sides of each stile,-that is the side which slides against the window stop, this wear stript being so arranged relatively to the opposing walls of the'stile, that a groove is provided at the inner edge of the stilefor receiving a removable glazing strip. The wear strip is also formed to provide a weather strip at the. outer edge of the sash in the sash guide. 4 i

Each stile'is provided with a wear strip on oneiside only, for the reason that the sash BEENFOROED TISIIIIIEILAJ'Jv WINDOW SASH.

is provided with means tending to force it toward either the inner or the outer stop.

In Figure 2 a double sash is shown and the inner sash engages the inner stop and the outer sash, theouter stop. The sashes are pressed toward the stops 'in any well known manner, and preferably sash locks are provided, which press the sashes toward one or the other of the stops, and as such sash locks are old and well known, and further as various forms of sashtighteners for forcing the sashes toward one or the other of the windowstops are well known, and in general use, further description is thought to be unnecessary. In so far as the wear strip feature of this invention is concerned, it is only necessary to bear in mind that the sash is pressed toward one windowstop only.

. In the double window construction shown,

the sashes are alike in construction, but are reversely arranged relatively to each other. That is the wear strip is on the outer side of the outer sash and on the inner side of the inner sash. Thefsash locks are located on the inner side of the outer sash and tends to press thesash toward the outer stop. The sash locks on the inner sash are also on the inner side thereof, but thelocking bolts are so beveled and coaot with the beveled rack or other means on the window frame as to pull the inner sash toward theinner stop. The sash is formed of top, bottom, and side mem beis, each' of which is formed up of sheet metal strips, the top and bottom members being usually called rails and the side members, stiles.

1 designates the stiles, each formed up of thin, sheet metal pieces as brass in the gen 'eral form of a rectangular tube, each stile being provided at its inner edge with a flange 2, forming one side of a channel for receivin a glass pane 3, the opposite side of this 0 annel being formed by a removable glazing strip to be hereinafter described. In Figure 2 the stile is formed of an outer body and an insert 4, the insert being angular, and one flange thereof forming the bottom of the glass groove, and the other flange lapping the inner side 5- of the,outer or body" portion of the stile. The flange 2 is formed double by doubling the same back upon itself at 6, and the insert 4 is provided with an angular flange or lip 7 extending between the double walls of the flange 2. These parts are secured together by any suitable means preferably by a'welding process or by rivets or-both..

8 designates the inner stop of the window frame.- 9 the outer stop and 10 the interconnected-to the top rail 1 1 by a beveled joint and to the bottom rail 15 by joints in which the ends of the bottom rail abut squarely against the inner sides of the stile. The wear strip is usually of brass and preferably secured to the stile by soldering or some other welding process. The wear strip is here illustrated as having an extension 16 lapping the outer edge of the stile body 1, and this extension is further provided with an angular portion 17 offset or spabed from the edge of the stile body and forming a weather strip, which coacts with a weather strip 19 associated with one of the window stops, as the intermediate stop 10, and extending into the space between the offset portion 17 of the weather strip, and the edge of the body. The weather strip is also provided with a portion 20 extending outside of the window guide and spaced from the underlying wall of the stile or body forming therewith a groove 21 for receiving the base of the glazing. strip 22.

.Each glazing strip 22 is preferably formed of sheet metalv and is doubled back upon itself, the double flange portion 22 forming the outerside of the channel for receiving the glass. The glass is usually provided with a resilient marginal channel piece 23, which fitsin the channel formed by the flange 6 and the flange 22 of the stiles and in the correspending grooves in the'top and bottom" rail. One of the sash members is formed with a glass receiving channel, the opposite walls'of which are permanent, while the other members are formed with a removable glazing strip as seen in Figure 4, and preferably the top or bottom rail is formed with the glass receiving groove having both its opposite walls permanent, andin the illustrated form p of this invention, the bottom rail is formed with the glass receiving channel having permanent walls. V

The lower rail 15 is formed up of sheet metal in'the form of a channel the bottom of which is provided with a reentrant groove 25 for receiving the margin of the pane-0f glass,

- and its metal covering 23. This reentrant groove may be formed in any suitable manner, but ther'walls 26 thereof are'permanent.

That is neither of them is removable. Also a rubber bu'fl'er 27 is provided at the lower edge of thebottom rail for engaging the sill.

The top rail 14 is also formed up of sheet metal and provided with a glass receiving channel, one wall 28 of which is permanent and the other wall of which is formed by the removable glazing strip. The top wall is further provided with a metal strip 29 correby insetting the part of theopposing wall 34 of the-top r'ail body. That is the part of the wall opposite the strip 29. The glazing strip 33 is similar to the glazing strip 22 with the exception that the walls of its folded flanges are not spaced apart.

The stiles of the sash are joined to thetop rail by a miter joint, and likewise the wearing strips 13 and strip 29 are mitered at their abutting ends. Theglazing strips along the top rail and along the stiles interlock at their abutting ends and. as here illustrated their abutting end edges are angularly disposed or. mitere The glazing strips 22 along the stiles are, however, square or straight at their lower ends andabut against the horizontal edges of one of the flanges 26 of the bottom rail. Owingto the interlocked or angularly disposed, mitered, abutting ends of the glazing strips 22 and 33 along the stiles and the top rail and to the square lower rails of the strips 22, these strips hold themselves in assembled relation. Preferably, however, quick detachable means are provided which hold each glazing strip 22 from dislocation, and as here illustrated this means consists of alockingv member carried by the glazing strips 22 near their lower ends, and operable into and out of interlocking engagement with the bottom rail or the inner or outer flange thereof. This locking means on, each strip 221s here shown as a-latch or slide 36 movable between the double walls of the glazing strip portion 22 near the lower end thereof into a slot or open ing 37 in the edge of one of the flanges 26 of the bottom rail, the slide 36 having a short stem 38 which extends through a slot 39 in the lower end of each glazing strip 22 to the outsideof such strip where it is provided with a head or finger engaging member 40.

In Figure 5.the stile is shown as formed with a removable glazing strip 41 similar to that shown in Figure 3, the base portion 41* of which is located in a groove formed by the insetting portion of the wall42 of', the stile underlying the wearing strip 43.

In Figures 6 and 7 ditferentform-s of stiles areshown and in Figure 6, the wearing strip 44 is shown as closing the'open outer edge of the stile body 44*, and as secured to an angular lip 45 on the stile body and secured thereto, this-lip 45 and the contiguous portion of the strip 44 constituting a Weather strip. In Figure 7 the weather strip 46 is provided by an angular extension of one of the walls 47 of the stile body. In both Figures 6 and 7, the

groove 48 or 49 for the glazing strip 50 is provided by insetting at 51 or 52 one of the walls-of the stile body.

In inserting a new pane of glass, it ismerely necessary to remove the glazing strips 22 and 33 by withdrawing the slide 36 by means of the finger piece 40 and swinging the glazing strip 22 inwardly toward each other, so that they can' be removed and after they are removed, pulling the glazing strip.33 out -of itsgroove 32. A new glass pane is then inserted by first setting its lower margln n the groove of the bottom rail and pressing thepane so that its side and top margins are against the permanent flanges or sides 6. and 28 of the glass receiving grooves of the stiles and the top rail.

The glazing strip 33 is then placed in position along the top rail and then the glazing strips 22 laced in position along the stiles-by first locatlng their miter upper ends in juxtaposition to the miter ends of the strip 33, then swinging these strips 33 toward the stiles pressing their base portions into the grooves 21 of the stiles until when they are fully placed in position. The lower ends of the strips 22 abuts squarely against the .upper edges of the flange 26 of the bottom rail and ordinarily on account of the squared lower ends of the glazing strips 22 and the beveled upper ends thereof, these strips 13 will stay in positionl However, as a precautionary measure, the locking means is provided and after strips 22 are properly located the slide 36 is moved downwardly by means of the finger piece or head 40 into the opening 37 in the bottom rail. I w

In the double window construction the glazing strips are preferably located on the outside of theoutersash and on theinside of the inner saslf and as the wear strips formone wall of the groove which receives the glazing strips, the wear strips are locatedon the outside of the outer sash, and on the desired. be employed, By this construction,
